We spent the last 12 months targeting a particular search term (mortgage broker) and have been ranking well for it consistently for about 6 months now. We have decided to change the target search term to something else (insurance broker) but noticed that our traffic has started to decline since we started doing this.
We are still ranking well for the initial search term, and our ranking is slowly improving for the new targeted search term in SERPs but traffic is down about 60% from January. Is it normal/expected for this to happen?
